People live in RVs. The real question is: is it practical to have an airship with the top covered in photovoltaic cells sufficient to run all your normal electrical needs? A residential-class airship would probably be limited to visual flight rules conditions and have to land or at least be docked every night. You'll want to do that for a variety of comfort reasons, too -- water is heavy, so finding a campground with electrical and water hookups would be preferred.
